Patented Dec. 10, 1940 UNITED STATES PATENT OFFICE 9 Claims,

This invention relates to refillable books, that is to say, note orcheck books of the type in which the leaves are removable from the coverand replaceable.

My invention is concerned with structural refinements in books of thekind referred to which make possible the quick removal and replacementof the leaf fillers; which effectively insure against the displacementof the leaf filler within the cover notwithstanding careless handling ofthe books; and which, moreover, permit the leaves to lie perfectly flatwhen the books are opened.

Other objects and advantages will appear from the following detaileddescription of the attached drawings, wherein Fig. I is a fragmentarylongitudinal edge view of a refillable book conveniently embodying myinvention, opened and with a portion thereof broken out and shown insection.

Fig. II is a fragmentary view in plan of the open book, likewise withportions broken out and shown in section.

Fig. III is a fragmentary view generally like Fig. I, but with the bookclosed.

Fig. IV is a view in turn like Fig. III with one of the cover wingsthrown open.

Fig. V is a fragmentary view in perspective of the cover of the book.

Fig. VI is a perspective view of the leaf filler of the book.

Fig. VII is a fragmentary detail view of the filler in longitudinalsection; and

Fig. VIII is a detail plan section of the filler taken as indicated bythe angled arrows VIII- VIII in Fig. VII.

As herein shown, my improved refillable book consists of a cover whichis comprehensively designated by the numeral I and separatelyillustrated in Fig. V, and a filler which is comprehensively designatedby the numeral 2 and separately illustrated in Fig. VI.

The cover I, it will be observed, hasa back 3 centrally between oppositecover wings 4 and 5 which are integrally united with said back throughflexible connecting portions at 6 and I. The cover wings 4 and 5 areformed with pockets 8 and 9 which are open toward the cover back 3 asshown in Fig. V, and provided with closure flaps l0 and II respectivelycapable of being retracted to render the pockets accessible for apurpose later on explained. As a convenient releasable means fornormally holding down the flaps l0 and H, I utilize snap fasteners ofwhich the socketed buttons l2 and I3 are secured to the flaps, and thecomplemental studs l4 and I5 to the cover wings 8 and 9 respectively.Permanently attached to the inside of the cover back 3 by one or moreclips such as shown at IS in Figs. I, III, IV and V, is a reinforcingmember I! which is fashioned to channel section from stilf sheetmaterial, preferably metal. The parallel side flanges of said member I!constitute inward ridge projections which are transversely notched atintervals as at l8.

As herein illustrated, the filler 2 (Fig. VI) includes a pack 2|] ofleaves with offset notches 2| along one of its short edges in whichflexible retainers 22 are lodged. These retainers 22 may be of textilecord as shown in Figs. VII and VIII. Applied to the notched edge of theleaf pack 20 is a coextensive elastic adhesive strip 23. The retainers22 and the strip 23 cooperate to effectively hold the leaves of the pack20 assembled as a unit. The leaves are in this instance perforated alonga transverse line 24 and also along parallel longitudinal lines 25 whichintersect with said transverse line, and are thus subdivided into stubs26 and check or receipt blanks 27. The pack 20 is, moreover, provided atthe top and bottom with auxiliary backing sheets 28 and 29 of relativelystiff material which correspond in area to the stubs 26 and which areintended to serve as covers for the stubs 26 when the check blanks 21have all been used. Other types of fillers may of course be provided inwhich the leaves are plain, ruled or otherwise subdivided and thebacking sheets 28 and 29 made coextensive in area with the leaves of thepack. As shown, the backing sheets 28 and 29 are glued fast to theoutermost leaves of the pack 20 along margins adjacent the bound edge ofthe latter as indicated conventionally at 30 and 31 in Fig. VII, andover the ends of the retainers 22. As another alternative, the fillermay be composed of a pile of loose leaves without the notches 2|. In anycase, the leaves are provided somewhat inward of one edge with elongatedapertures '32, which are spaced .to correspond to the spacing of thenotches It? in the flanges of the stiffening member I1 on the cover I.

Incorporated with the filler 2 is a binding element 33 fashioned fromrelatively tough flexible sheet material such for example as Celluloidor the like, having laterally extending tongues or straps 34 passedthrough the apertures 32 of the leaf pack 20. The strap-connecting barportion of the element 33 is loosely lodged between the folds of akeeper strip 35 whereof the coincident edges are united by adhesiveshown at 36 in Fig. VI, the tongues or straps 34 of said elementextending outward .through slits in one of said folds. For a purposealso later on described, the bar of the element 33 and the keeper strip35 are provided at their centers with openings 33a and 31 respectively.The outer ends of the straps 34 of the binding element 33 are lodgedbetween the folds of another keeper strip 38, and pairs of them atopposite ends of the series are secured by means of wire staples 39 toone of the folds of said strip, which fold is slitted, also as shown inFig. VI for passage of said straps. Coinciding edge margins of thekeeper strip 38 are united by adhesive as conventionally indicated at 40in Fig. VI; and said strip provided centrally with an opening 4!.

The manner of assembling the book is as follows:

The cover I is opened and laid flat with the pocket flaps It and Hunbuttoned and thrown back as in Fig. V. The filler component 2 is thenapplied and the anchorage strips 35 and 38 inserted into the pockets 8and 9 of the cover Wings 4 and 5, the bound edge of the leaf pack 29being incidentally placed into the channel hollow of the member I! andthe straps 34 engaged at the regions of their emergence from the pack,within the notches Id of said member. The pocket flaps I 0 and H arethereupon swung down to closed position and secured by the snap.fasteners l2, l4 and I3, I 5, of which the center ones respectivelyconnect through the openings 33a and 31 in the element 33 and strip 35,and through the opening 4| in the strip 38 to anchor the filler as bestshown in Figs. III and IV. In this connection, it is to be noted thatthe buttons and studs of the endmost snap fasteners interengage beyondthe end strips 35 and 33 as shown in Fig. II.

It is to be. furthermore noted from Figs. II, III, and IV that theopenings 33a and 31 in the bind ing element 33 and keeper strip areamply large to permit the straps 34 to reeve back and forth through theslits of said strip as the book is opened and closed. As a consequenceof this and due to the flexibility of the retainers 2-2 and the elasticstrip 23, which connect the leaves of the pack 2%, the book will lieperfectly fiat when open as shown in Fig. I, which is particularlyadvantageous with check books in that it facilitat-es filling out of thecheck stubs.

Preferably, the filler is made up for the market as shown in Fig. VIcompletely assembled with the binding element 33 and the keeper strips35 and 38', and the intention is that said element and strips bedetached and discarded upon exhaustion of the checkblanks and removal ofthe stub pack from the cover I.

The invention is of course not to be regarded as limited to the precisedetails of construction hereinshown byway of example since, as will bereadily understood by those familiar with the art, these are susceptibleto considerable variation within the scope of the broader of theappended claims and as necessitated by the prior art.
